The ASDSO Dam Incident Database provides basic information on dam safety incidents to ASDSO members, dam safety stakeholders, the media and the public. The database began as a cooperative effort between the Department of Homeland Security Dams Sector and ASDSO in 2010. The initial database contained a limited number of dam failure records from a previous ASDSO dam failure database effort. In 2010, ASDSO began to gather dam safety incident information (both failure and non-failure) from the state dam safety programs. The majority of the incident records have been collected from state programs following the year in which they occurred. Some states have been able to provide historic incident information and ASDSO will continue to obtain as much information, both current and historic, as possible. The database is not considered comprehensive of all dam safety incidents, both historic and current, and reflects only the data that ASDSO has been able to collect. Much of the identifying information on specific dams is obtained from the National Inventory of Dams. ASDSO does not provide assurance that all the information in the database is completely accurate. It is the best information available to us at the time, however it could be subject to error or misinterpretation. If you see an error or have additional information to provide for a specific incident, please contact Mark Ogden at [email protected]. If you would like to provide additional incident information to the database, please contact Mark. ASDSO has a spreadsheet (download at this link) that provides an explanation of each field and can be used as an entry form to submit incident information.
Using the Database: The following search table allows the user to view, search and select records of the ASDSO Dam Incident Database. The columns represent a few of the fields of the database that contain what can be considered the major incident fields. They can be sorted in ascending or descending order by clicking on the arrows next to the field name at the top. To see more information on an incident without leaving the search table click on the blue “+ sign” at the left of an incident row. You can then click on the red “- sign” to collapse the additional fields. To go to an individual incident page, click on the dam name. Users can filter search results by each field using the search criteria boxes at the top of the page. Multiple filters can be applied. Some fields have fixed possible entries and those are presented in the search box as a drop-down selection. Users can also download a CSV (Microsoft Excel) version of their search by clicking on the “Export Table to CSV” link. To download the entire database, click on “Reset All Filters” and then “Export Table to CSV.”
- If a field is empty, that indicates that there is no value for that field in that particular record.
- There are a few incident records with an incident date in the 1800s. When downloaded to CSV, those dates become "General" format instead of "Date" format which can impact sorting and searches in the Incident Date field in the CSV file.
- A few incident records have reports and photos, etc. associated with them. In the individual record page there is a field named "Attachments" and if it has a value of "Y" then there is some associated attachment. Contact Mark Ogden if you are interested in more information on that record.
- ASDSO does not become aware of many incidents until states report them in an annual performance data call. As a result, incidents from the current year and even some from the previous year will not yet be in the database. Incident information is not necessarily entered in chronological order. Data is entered as it is received and as time permits; some more recent incidents may be included before older incidents. The database was last updated on January 6, 2025.

In an apparent attempt to divert water into the other channel, he built a berm through the channel in question. Apparently the berm overtopped and failed, letting water once again flow through the channel and continue head cutting. At some point, it appears that the reservoir overtopped the dam crest slightly but no visible damage was seen on the embankments. | P | RE | R | N | 35 ft | 988.00 | 50.00 | 1977 | MO31108 | TR-BARNES CREEK | 37.1409 | -90.2424 | NONE | |||||||||||||||

The immediate post-Irene inspection did not reveal any change in the size of the void, but 11 days after the storm a sinkhole developed near the left upstream corner of the spillway. The remaining flashboards were removed from the spillway to lower the pond level below the spillway elevation and the void was filled with concrete on 9/9/2011. Subsequent repairs will be made to seal open construction joints and cracks in the spillway slab, which are thought to be the source of leakage through the slab that caused the void to develop. | S | REPG | RF | N | 15 ft | 611.00 | 48.00 | DE00070 | BEAVERDAM BRANCH | 38.904 | -75.4848 | DNREC | |||||||||||||
